Colorado Parks and Wildlife is offering free state park entry on Black Friday, encouraging people to get outside as a “unique alternative” to Black Friday shopping, according to a CPW news release.

“Fresh Air Friday” offers both Coloradans and out-of-state visitors an opportunity to explore state parks throughout Colorado free of cost, the release said.

“What better way to spend the holiday season than exploring one of Colorado’s amazing state parks,” Gov. Jared Polis said in the new release. “Fresh Air Friday is a great opportunity for Coloradans and out-of-state visitors to take advantage of free access to the parks, try a new outdoor recreation activity, and spend time with loved ones.”

Colorado has 43 state parks, and the seven closest to Denver include the following.

• Barr Lake State Park, 13401 Picadilly Road, Brighton: 2,715-acre park that includes a reservoir, wildlife refuge and opportunities for birding, fishing and boating.

Along with free state park entry, CPW is also discounting their retail items online and at state park visitor centers, offering a 25% discount shop-wide, the release said. The discount does not apply to ammunition, gasoline, food, firewood or certain passes and licenses.

CPW also encourages people to opt into the Keep Colorado Wild pass with their vehicle registration. The pass is a $29 addition to registration fees and gives the registrant entry to all of Colorado’s state parks for a year. Funds from the pass go toward state park maintenance, search and rescue efforts, avalanche safety and outdoor education.
